Do You Have a Faith Your Kids Can "Catch"?

When I was writing my book, Head & Heart, I kept hearing over and over again from men and women I spoke with that when it comes to raising children in the Catholic faith, “Faith is more caught than taught.” But what does it look like to have a “catchable” faith? How can we know we are on the right track in witnessing a kind of faith that our kids (and others!) will want to embrace fully themselves?
